[cobirds] RMBO Banding Station Report, Chatfield, 5/19/13

Today was much like yesterday – cooler weather and somewhat more birds.  22 birds banded, plus 2 returns from prior years:

 

Least Flycatcher                1 (FOS)

Swainson’s Thrush          1

Gray Catbird       3 new, 1 return (Banded 2012)

Virginia’s Warbler            1

Yellow Warbler 2 new, 1 return (Banded 2010)

MacGillivray’s Warbler   2

Wilson’s Warbler              1

Yellow-breasted Chat    2

Green-tailed Towhee    1

Spotted Towhee              1

Lincoln’s Sparrow             3

White-crowned Sparrow, Mountain        3 (All White-crowneds before today were Gambel’s.  Do the Mountains move later?)

Red-winged Blackbirds  1

 

It now “feels” like the bulk of migration should be happening –the weather is right and most of the trees and bushes seem to be filling out.   Or, maybe the birds are just going to drift through slowly – the opposite of last year, when they seemed to go immediately to their breeding grounds.  (For comparison, today, with 2 of our 5 weeks still remaining, we passed the total number of individual birds caught last year.)  Early spring v late spring.  Sheesh.

 

Open daily, weather permitting, through June 2.
